ans -> 0.7

[(3^4)^(3/4) / root(9) ] * 3*(3^0.5) = 3^(5x)

=>[3^3 /3] * 3^1.5 = 3^(5x)

=> 3^2 * 3^1.5 = 3^(5x)

Now equating both the sides ,

2+1.5 = 5x

=> 3.5 = 5x

=> x = 0.7

0.7

what is this bar denote ??

ans -> 64

1st u hv 2 calculate 1/3+1/2

thanku đź™‚

its verniculam .. a spcl bracket which has the highest priority a/c vbodmas

v= verniculam (bar)

6th ques me downstream time 12 min se less ni hoga ???…….did u get it

pehle bar ko solve karo then bracket….

7 no question upstream ,downstrean ..in both cases ..taking the same time ..how it is ?

It takes 6 hours only in upstream direction

yes u r right ….

abs should be =5/3 or 3:36 hrs

The 6 th question is realy stupid… How can it be solv dat way???!

first of all dear aspirant….b4 making any comments to any question first try to understand what the question is trying to say make a virtual diagram in mind about the things quantitys given and thn try to crak the logic and solve dont just by seeing any type questions specially in word problems u can make any final comment abt stupidity and all that so..only word problems are word problems and difficult to crack…

yes updated..

mam in 6th question ….time should be less than 12 minutes because this time she going downstream ???.why we take same

see here miss…12 mins gaya 12 mins wapis aaya toh totl tym 24 mins hoga na question kh rha h ki 12 mins jaise hi wo tavel krti h usko pata chlta h so ans so…fr wo wapis aayi naa usi pint mn to 12 mins usko tym lga jitna b distance usne cover kia tha utna hi usko lgega wapis usi point mn aane mn toh totl tym 12+12 =24 mins hi hoga..:)

yaa mathmetically samjiye

downstream tym =-12 mins jo aap kh rhi

upstream tym =+12 bcz against work kr rhe h

=> time diff =12-(-12) =24mins theory ya mathematical both has same ans..:)

Really?!!

yess if u go frm home to a certain place after a certain time say 10 mins u forgot to take something then assuming the constant spd how much totl tym will u take to come back say u started ur journey at 10am after 10mins u realise it then at wht tym u will reach back to home 10.20am or 10.10am think abt it if this is cracked u will get my point what i am trying to say and wht the question is trying to say…:))
